Short answer: these are not really competing for the same job. The Partybox Encore Essential ranks #7 of 75 boombox speakers, while the Xtreme 5 ranks #2 of 78 large speakers, and the Xtreme 5 costs $70 more.
The core tradeoff is plugged-in power versus all-day portability. Our notes call the Encore Essential a great sounding party speaker with somewhat boosted bass, backed by a 135mm woofer and 100W RMS output, but it only lasts 6 hours on battery at medium volume and carries a poor IPX4 water rating. The Xtreme 5 is described as a fantastic sounding speaker with excellent off-axis dispersion and bass reaching well below 40Hz, a big step up from older JBL portables, and it runs 28 hours on a removable battery with IP68 protection against dust and submersion.
The Xtreme 5 is not without its own issues. Our notes flag some bass boost, a hole in the mid-upper bass that cannot be EQ’d out, and default EQ presets that are weak enough that reviewers recommend a custom EQ to get the best sound. It is also heavier and bigger than its predecessor, the Xtreme 4, and it costs more than the Encore Essential to begin with.
What the Encore Essential adds that the Xtreme 5 lacks: a wired aux input, USB playback, and true stereo output from its cabinet, versus the Xtreme 5’s single-woofer partially stereo design.
Buy the JBL Partybox Encore Essential if you mostly run it plugged in at home or for parties near an outlet, and want true stereo sound and USB playback.
Buy the JBL Xtreme 5 if you need a speaker that travels, survives water and dust, and delivers deeper bass without being tethered to a wall outlet.

JBL Xtreme 5: $399.95 Amazon B&H Photo Video eBay
Pros: Removable battery. Quite deep bass, reaching well below 40Hz. A fantastic sounding speaker with excellent off-axis dispersion, a big step up from older JBL portables. Beats the Soundcore Boom 2 and Tribit Stormbox Blast on bass depth and clarity. Plays clean at volume, unlike the JBL Boombox 4.
Cons: High priced. Some bass boost. A hole in the mid-upper bass which can’t be EQ’d out. Default EQ presets are weak (Signature is boring, Chill and Vocal are close to unusable) - needs the custom EQ to sound its best. Bigger and heavier than the Xtreme 4.
Setup: Try this Oluv EQ for the most neutral sound
